I just don't know how to go about doing that seamlessly along the length of the path. But, if I can print a 2% dot, I can in the file, create a blending with that 2% that looks like it reproduces 1%. There's no way to overcome the mechanical capability of the press-if it can't print a 1% dot nothing you do to the file will change that.Īccurate. I would say you're accurate - not really making a color separation. There is no color in the process channels. The monotone photoshop file setup as a spot channel is linked within Illustrator and exported as a PDF. My layering mention is complicating things but not associated with the desired outcome. I'm not having trouble getting the spot to print just a percentage reproducing within the print.
2 COLOR PROJECT MAGENTA CHANNEL SPOT COLOR PDF
If the press is capable of printing CMYK + a spot color, and you want to spec the extra plate, you have to set the spot color plate up as a Spot Channel in a CMYK mode file, or assemble the page in InDesign where the spot color could be placed as a Monotone and a 5-color PDF can be exported. When lights of different colors shine on the same spot on a white surface, the light reflecting from that spot to your eyes is called an additive mixture.

Use this graphic as a quick reference to important basics for choosing between additive and subtractive colors for your next project.Your "layer" description makes it sound like you are really not making a spot color separation. Because of this, the RGB colors on a monitor do not always equally translate into CMYK colors when printed on paper or other substrates. Limited by the ink pigments and tints, a printer can only replicate several hundred thousand colors. Subtractive colors use reflected light, so they appear muted in contrast. If the final product will only appears on a screen or monitor, keep the color mode as RGB.īecause additive colors use transmitted light, the colors appear much brighter and create a larger visible spectrum, producing millions of colors on a screen. If the final product is for print, remember to convert the color mode from RGB to CMYK. It is important to choose the correct color model at the beginning of the project to get the best results. Hence, the unit of measurement for a print graphic is DPI (Dots Per Inch). The various tints are then printed in overlapping patterns to create a picture. The overlapping dots create the illusion of a hue. A tint is a screen of tiny dots appearing as a percentage of one color. On a piece of paper, cyan, magenta, yellow and black pigments are distributed by the print head in tints. Black is referred to as "K," or the key color, and is also used to add density. To produce a true black, black pigment is added. In theory, adding equal amounts of cyan, yellow and magenta will produce black, but in reality, the result is often a very muddy dark brown. Printers use cyan, magenta and yellow inks in various percentages to control the amount of red, green and blue light reflected from white paper. Subtractive color begins with white (paper) and ends with black as color is added, the result is darker. The subtractive colors are cyan, yellow, magenta and black, also known as CMYK. This color model is used in printing, silk-screening, painting and other mediums that add pigment to a substrate. In the subtractive color model, pigment is used to produce color using reflected light. Hence, the unit of measurement for a digital graphic is PPI (Pixels Per Inch). The pixels are then formed like tiny mosaics to create a picture. By combining the three colors, the desired hue is created in one pixel. On digital devices, a red, green or blue element is activated by an electrical charge causing them to glow. When all three colors are combined equally, the result is white light. As more color is added, the result is lighter. Additive color starts with black and adds red, green and blue light to produce the visible spectrum of colors. The additive colors are red, green and blue, or RGB. The additive color model describes how light produces color. Additive ColorĬameras, televisions, phones and computer monitors use the additive color model. Additive and subtractive color models are an application of color theory. Understand the additive (RGB) and subtractive (CMYK) color models and which to use for your next project.Ĭolor models explain how colors work, interact and how we replicate color.
